Analog Devices Inc./Maxim Integrated MAX9152ESE

Overview

MAX9152ESE from Maxim Integrated is an 800Mbps LVDS/LVPECL-to-LVDS 2×2 crosspoint switch with pin-programmable configuration, ultra-low 120ps_Pk-Pk (max) PRBS jitter, and 50ps (max) channel-to-channel skew. It operates from a single +3.3V supply over –40°C to +85°C and supports 2:1 mux, 1:2 demux, splitter, dual repeater, and crosspoint modes for high-speed signal routing in telecom infrastructure.

For engineers reviewing the MAX9152ESE datasheet, MAX9152ESE pinout, MAX9152ESE application, or MAX9152ESE equivalent, key selection criteria include differential input compatibility with LVDS/LVPECL, selectable 75Ω/100Ω output impedance, low-power 109mW operation, and deterministic switching timing under 3.5ns.

Technical Context

The MAX9152ESE implements a fully differential CMOS switch matrix with LVCMOS/LVTTL control logic (SEL0/SEL1/EN0/EN1) governing signal path selection and output enable states. Its internal architecture supports simultaneous bidirectional routing of two independent differential data streams without internal termination or level-shifting circuitry.

It features programmable differential output resistance (60–155Ω) via NC/RSEL pin, fail-safe input biasing support via external resistors, and propagation delays under 2.9ns with pulse skew ≤90ps. All AC performance metrics-including jitter and skew-are specified at 800Mbps using PRBS23 pattern and 200mV differential input voltage.

Key Specifications

Pinout & Package

The MAX9152ESE is housed in a 16-pin SO (Small Outline) package with standard 1.27mm pitch, JEDEC MS-012AC compliant footprint, and exposed pad not present. Pin 9 is no-connect; all power and ground pins are dedicated (Pin 5 = VCC, Pin 12 = GND).

FAQ

What is the maximum supported data rate for the MAX9152ESE?

The MAX9152ESE is characterized and guaranteed to operate reliably at 800Mbps using PRBS23 test patterns. This data rate is validated across the full –40°C to +85°C temperature range and ±10% supply tolerance. While some units may function beyond 800Mbps under ideal lab conditions, the MAX9152ESE specification does not guarantee performance above this rate, and system-level timing margins must account for worst-case jitter and skew at 800Mbps.

Does the MAX9152ESE support PECL input signals directly?

The MAX9152ESE accepts LVPECL signals directly without external components, as confirmed in the General Description and Applications Information sections. For standard PECL (not LVPECL), an external attenuation network (e.g., Figure 9 in the datasheet) is required to shift the common-mode voltage into the MAX9152ESE's valid input range. The device's differential input threshold is specified at ±100mV, and PECL compatibility depends on proper level translation to meet that window.

How is differential output impedance selected on the MAX9152ESE?

Differential output impedance on the MAX9152ESE is selected via the NC/RSEL pin (Pin 8). When NC/RSEL is driven low or left open, the output resistance is configured for 75Ω loads (60–118Ω typical range). When NC/RSEL is driven high, it selects 100Ω load matching (85–155Ω typical range). This selection directly affects reflection coefficient at the driver end and must match the characteristic impedance of the PCB trace or cable used in the design.

Can unused differential inputs on the MAX9152ESE be left floating?

No, unused differential inputs on the MAX9152ESE must not be left floating. Per the Applications Information section, each unused INx+ should be pulled to VCC with a 10kΩ resistor and each unused INx− should be pulled to GND with a 10kΩ resistor. This prevents noise-induced switching in the high-speed input comparator stage and ensures predictable high-impedance behavior at the output when the input is undriven.

What is the power dissipation of the MAX9152ESE under typical operating conditions?

The MAX9152ESE dissipates 109mW total under typical quiescent conditions at +3.3V and +25°C, as stated in the General Description. At 800Mbps switching, supply current rises to 52–70mA depending on load and configuration, resulting in 172–231mW power consumption. Thermal design must accommodate this range, especially in sealed enclosures or multi-device layouts where ambient temperature may exceed +25°C.
